Ignition Switch

[Boxadog 2000]

The bike has had an intermitent fault which I finally traced today not one but two chaffed wires going into the ignition block the bike would cut out momentarily when pulling away from a t junction ie when the bars were turned nearly fell off once or twice.

The green wire and the purple were broken almost completely through

Where was the chafe? Where were the wires rubbing?
I checked my wiring bundle near the fusebox and, yes, the fairing had been rubbing through the outer black wrap. I guess we all need to check these vulnerable points.

The breaks were right at the bottom of the ignition switch

Another common fault.

My wires did completely come away from the ignition block but I got the whole assembly replaced for nowt.. how?

If you have BMW Emergency Assistance, just call 'em out and report the bike won't start at all (you'll have to go down the stupid question list first). I had (as usual with BM's EA) excellent service and the block replaced for free (which is more than the cost of the EA).

Otherwise it's a self repair job or a wander down the parts dept.

Headline in local Berkshire newspaper;

'Obsessive cleaning blamed for wearing through wires, Shock'

cleaning the wires?? what a waste of time. I have polished the ally tank though!

Oyster,
Hope its out of warranty.
Page 72 of the good book 'warning: note that aluminimum surfaces form a natural oxide surface. For reasons of strength, this protective layer must not be removed from the fuel tank'

Probably adding strength to the forks, yoke, brakes and engine of all of our bikes.

Symptoms: Cuts out for no reason, ususally making a turn. I have had that a couple of times, not only nearly of as a result, on occasion it can leave you in a position where you really need the power on sharpish.

Where do I give closer inspection? This site has the answers before the question is asked.

Thanks

Mark after much head scratching I found the best way was to put the bike in the centre stand and just keep turning the bars from lock to lock eventually it will hicup or just plain cut out.
